Question

Write a translation rule that maps point D ( 7 , − 3 ) onto point D ' ( 2 , 5 ). I NEED HELPPPP!

Answer 1

5 places to the right on the x-axis and 8 places up.

Explanation:

(-5,+8)

Answer 2

`T_( - 5 ,</p><p>8) \: or \: D'(x,y) →D(x - 5,y + 8)`

Explanation:

`T _ { ? ,</p><p>?}`

`D'(x,y) →D(x \pm ?,y \pm ?)`

given D : (7,-3), and D' : (2,5)

the coordinates of D can be represented as (x1,y1), and the coordinates of D' can be represented as (x,y).

you can simply take the difference in the x values and difference in the y values from the preimage to image.

like this:

f'(x,y) → f(x+(x-x1),y+(y-y1)) :
`</p><p>T _ {(x-x_1),(y-y_1)}`

D'(x,y) → D(x+(2-7),y+(5--3))

D'(x,y) → D(x-5,y+8) :
`</p><p>T _ {-5 ,8}`
